Am looking to change my current setup to a REALLY comfortable coilover setup and based on a fellow forummer's review and a well made video review, i have been led to believe that RS*R Black-i is the way to do (for my budget).

"More comfortable than the stock setup" has been mentioned a couple of times in the review of the Black-i vs Sports-i vs the something else-i.

My question is:

The Black-i has a spring rate of 7F/7R while the sports-i (supposedly less comfortable) has a spring rate of 6F/7R. While i believe the dampers are tuned differently, can a coilover with a stiffer spring rate really be that much more comfortable??

Isnt the role of the springs to absord the shock??

Sorry for the long ass question, i am really picky about ride comfort. It must be softer and more compliant that stock setup!

Thanks!!
The Sport-i is what you want; the black-i is for slamming the car. PM us for a quote

@CSG Mike will say SPL. And he's right, it's a top notch product. You could do Cusco, Whiteline, or GTSpec as well.

So can I safely assume that you also prefer the SPL lower control arms as well?

I have KW V3's

Thanks for the reply

Correct, and that is what we use on our shop BRZ (and soon on the WRX).

To answer your question, YES you can improve ride comfort while still increasing spring rates. BUT the damper likely won't be cheap.

A very important note: better than stock to one may be much worse than stock to another. It depends on your roads, your expectations, and what kind of bumps bother you. Many will say that their set-up rides "better than stock" but in reality, it's just "different than stock."

I've been on coilovers that swallow up wheel bending potholes without issue, but make the man boobs you didn't know you had jiggle all day going down a concrete stretch of highway. And vice versa...coilovers that are smooth as silk on mostly good but maybe a little choppy pavement, and they make you hit your head on the ceiling on a larger sharp bump.

Both of the above were running stiff rates and could have used some damper tuning. With a little more work they could have had the best of both worlds.

So yes, you can make a coilover with firm rates ride smoothly. It will, however, be easier to make a system that rides well if you're sticking with mild/medium rates as long as you have the travel and good damping. The really excellent damping needed to make very stiff rates ride well generally costs some decent money.

Thanks both for your comments. Really appreciate your ideas.

@Andy RCE, maybe a little bit more information for ya.

I totally understand the damper vs harder riding springs idea. Thanks!
Currently am running Swift Springs on stock dampers. While on the topic of ride comfort, generally the ride comfort on the Swifts are ok, bearable, but harder riding than the stock setup.

The road conditions here are quite poor, roads full of potholes and poor repair jobs.

What I am looking for is a suspension that can deal with the sharp bumps and stretches of uneven roads without breaking my spine. The stock does a decent job, the Swifts, not so good with that.

In a nutshell, the more Camry the better.
Hahahah!

If not RS*R’s are there any decently priced coilover that can give a soothing ride? Was also considering HKS GT, spring rates are lower (esp the rears). Will keep reading up and finding out more


@Mike CSG
Any reason for saying the Sports-I is better? Is it due to damper valving or have you tried them both?
Am not really going for low. Low is a bonus. Will PM you, maybe easier to share your ideas via PM.

The sport-i is made for comfort; the black-i is literally designed with a shorter damper to accommodate cars with 3" or more drops.

The US spec sport-i has lower spring rates and utilizes the OEM top hats for a softer ride, compared to the JDM spec or CSG spec sport-i.

I see!
How does it fare on rubbish roads? What settings are the dampers on?

Settings will vary by car; it's difficult to say blindly, but it's single adjustable so it's easy to play with.

You might also consider just adding Bilstein HDs to your set-up.

I was actually thinking about that...
But was thinking of the Koni's instead of Bilstein HD (which btw its the B6 or B8???)

I thought that Koni's twin tube low pressure gas dampers may yield a better (more comfortable) ride than Bilstein's high pressure monotube. But that is just my theory.

Well, my friend has ordered a set of your RCE Yellows and Koni's so i will take a taxi ride in his car and i reckon if his koni's can handle the Yellows, it should also do well for my Swifts no??


But coils are tempting for one reason, i find my ride height abit too low... Needs a lift cos i have slight scraping issues with the ramps in my carpark....

Sorry, Bilstein B6 = Bilstein HD.

Definitely go for a ride with your friend to check it out. Konis will do well with Swifts. Our springs are a little taller and use replacement shortened bumpstops so the ride may be slightly better with our springs, but you'll still get a good idea of what to expect.

Both are good shocks...IMO Bilsteins ride better over big bumps, but Konis are a little smoother over small stuff.
